Status of Soil Borne Diseases of Brinjal and The Frequency of Associated Pathogens

Status of Soil Borne Diseases of Brinjal and The Frequency of Associated Pathogens

Brinjal crop suffers many biotic stresses including soil borne diseases. Studies were carried out from 2007 to 2009 with the objective to know the status of these diseases, causal agents involved and frequency of the pathogens associated. The soil borne diseases were found to prevail in all the areas surveyed. The pooled data of the years 2008 and 2009, indicated that per cent seedling mortality and wilt incidence ranged from 13.25 to 29.50 and 16.05 to 37.55 per cent, respectively. Pathogenicity tests indicated that Fusarium oxysporum f. sp. melongenae (Fo), Pythium aphanidermatum (Pa), Rhizoctonia solani (Rs), Meloidogyne incognita (Mi) and Ralastonia solanacearum (Ra) were the causal organisms associated with the soil borne diseases of brinjal crop.
